Hippo is a collection of well crafted go packages that help you build robust, reliable, maintainable microservices. It is not a full-fledged framework with lot of magic, predefined architecture, specific patterns and bullshit opinions so you will be the one behind the wheel. It provides libraries to implement components for service discovery, async jobs, authentication, authorization, logging, caching, metrics, tracing, rate-limiting...etc which are essential requirements for running microservices in production.

QUESTION
I have 2 pandas dfs (df1 & df2) as seen here:
df1 col1 col2 col3 col4 col5 row1 Dog Cat Bird Tree Lion row2 Cat Dragon Bird Dog Tree row3 Cat Dog Bird Tree Hippo row4 Cat Tree Bird Ant Fish row5 Cat Tree Monkey Dragon Ant df2 col1 col2 col3 col4 col5 row1 3.219843 1.3631996 1.0051135 0.89303696 0.4313375 row2 2.8661892 1.4396228 0.7863044 0.539315 0.48167187 row3 2.5679462 1.3657334 0.9470184 0.79186934 0.48637152 row4 3.631389 0.94815284 0.7561722 0.6743943 0.5441728 row5 2.4727197 1.5941181 1.4069512 1.064051 0.48297918The string elements of the df1 correspond to the values of df2. For both dataframes the condition exists that an element (or a value) does not repeat on the same row. But can be repeated on different rows.
For example Dog of row1 = 3.219843, bird of row3 = 0.9470184, bird of row4 = 0.7561722 etc.
I would like to extract the values for all unique elements of the 1st df into different arrays. Like:
Dog = [3.219843, 0.539315, 1.3657334]
Cat = [1.3631996, 2.8661892, 2.5679462, 3.631389, 2.4727197]
etc...
Any ideas?
Many thanks!
...ANSWER
Answered 2022-Apr-10 at 18:17Assuming that your first columns df1 and df2 are the index of their respective df, we can extract the values for each unique animal in df1 by using the first df as a mask to extract all wanted values from the second one (the result is a new df with NaN in irrelevant cells, which can be turned into a 1-dimensional array with .stack().values).
First of, create some test data. Please provide it in a form like this in future posts. That's what @mozway was talking about in the comments. It is greatly appreciated.
(It's not always the case that somebody is willing to do all the copy-and-pasting necessary to get dataframes up and running for testing.)
QUESTION
I am trying to write a function that accepts an array of strings as an argument. I want to return the array of strings sorted first by number of vowels and then alphabetically.
Input: ['dog', 'cat', 'elephant', 'hippo', 'goat'] Output: ['cat', 'dog', 'goat', 'hippo', 'elephant']

QUESTION
I have a class containing a mixture of @abstractmethods and normal implementation methods, and I'm wondering how I should go about testing the normal implementations.
Quick Example: I'd like to test the zoo_str method, even though it depends on the abstract description method. If I have 100 animals, it seems like overkill to write a test in the Lion class, the Antelope class, the Hippo class, etc. What's the best way to do this -- my intuition says I should try to mock description, but I can't instatntiate the class and this falls apart if the abstract method is private (_description).

QUESTION
I have a const object with known keys. Each item may or may not have a specific property. I want a function to, given the key, return the value along with it's appropriate type.
I'm using TypeScript 4.6.2.
Of course I can just type in data.key?.property but I need to do this programatically.
Here's a contrived example to show what I'm after:
...ANSWER
Answered 2022-Mar-08 at 20:18In this situation I'd recommend using a generic signature on personLoves to capture the idea that name is a specific key of data. That will allow TypeScript to track the correct associated return type based on the value you pass when you invoke the function.
In combination with that, I would use an overload signature to capture the two situations you have: when the data for the person contains a loves key (in which case we infer the return type from the type of that key's value), and when it does not (in which case the return type is always undefined).
QUESTION
I want to fill NAs using the most recent data and have it apply to groups.
This is my dataframe
...ANSWER
Answered 2022-Feb-28 at 21:49The problem with the code you have is, pandas GroupBy Object doesn't have sort_values method.
So,first group the dataframe by pet, then apply a function which does forward-fill on each group by sorting the dataframe on id.
The reamaining part of sort_index, and reset_index is there just to get the resulting dataframe in the initial order of pet, and id columns.
QUESTION
I'm creating a shared component for a multi-select dropdown in Blazor server-side. SelectMultiple.razor child component is not passing selected values back to the parent index.razor page. EventCallback SelectedItemChanged in child component doesn't seem to be triggering. Can anyone help me out please?
Below is SelectMultiple.razor
...ANSWER
Answered 2022-Jan-24 at 00:51This happens because you raise the event only when the List variable changes, which in your code happens only once, during component's initialisation.
The source of confusion is that, during the entire component's lifetime, this List variable points to the same object, so it doesn't change. The contents of that list changes, yes, but not the reference to the List itself.
As a starting point, I recommend to add the InvokeAsync() to the FilteredItemChanged() function. You can figure out the rest from here.
This docs article explains the basics around parameter binding in Blazor. Also, check the answers to this SO question, they might be a bit easier to understand.
QUESTION
I just bought a new machine and made a fresh installation of Ubuntu 21.10 since I've read that the newer kernel works better with graphics drivers. I'm planning to update to the 22.04 LTS when it will be available. I didn't realize, however, that I might run into challenges with R.
There are plenty of questions here in SO on installing R on Ubuntu, but none seemed recent enough to address the Ubuntu version 21.10.
Ubuntu Packages For R - Full Instructions state that
As of May 19, 2021 the supported releases are
- Hirsute Hippo (21.04, amd64 only)
- Groovy Gorilla (20.10, amd64 only),
- Focal Fossa (20.04; LTS and amd64 only),
- Bionic Beaver (18.04; LTS), and
- Xenial Xerus (16.04; LTS).
So, if I understand correctly, I have three options:
- Uninstall 21.10 and replace with 21.04
- Wait for support for 21.10
- Install R from source
Now, the question is, have I understood correctly, or could I use, for example, the 21.04 repository (hirsute-cran40/)?
ANSWER
Answered 2021-Dec-22 at 19:11Apparently, it is ok to use a repository of older releases.
I was encouraged by Andre Wildeberg (thanks!) and added the 21.04 repository (hirsute-cran40/) into my /etc/apt/sources.list:
QUESTION
I'm having an issue with the download handler from shiny (downloadHandler) and rendering a table using DT (using renderDataTable). When I use the download handler and render the table in my flexdashboard application, the pagination gets cut off. Thus, the user cannot switch to different pages of the table as the pagination doesn't fit the container or "the box" that renders the table. This only happens when I include the downloadHandler. If I include buttons using the extension from DT, the pagination does not get cut off. The problem is that I need to use the downloadHandler as the amount of data in my application is quite large. Please note, the example data is not representative of the size of the data. Does anyone know how to fix this issue?
Here is the code that I'm using:
...ANSWER
Answered 2021-Dec-15 at 19:23After much trail and error, I have found a working solution. I have changed the overload from hidden to auto using a css chunk. This chunk makes the pagination show up when the table overflows the container. ```{css my-style, echo = FALSE}
QUESTION
Writing an uber clone through Android Studio, first time using Firebase. However, every time I click register user I get an error and nothing is entered.
When I'm on the emulator, I go to the DriverLoginActivity, enter my details for signup, no matter what is entered I get the Please check username and password requirements. But they all match, email format & password is over 6 digits. No matter what I do, I can't get it to register new users to the database
Firebase is connected, with dependancies all set up. JSON imported and correct SHA1 key. I've tried it on emulator and on my phone so I know its not the internet. Cannot figure it out for the life of me.
Firebase is set to Realtime database, with email and password authentification. Read and write rules are also set to true.
ANY insight would be hugely appreciated.
